| 摘 要： | 在吉林省蛟河市对玉米进行"3414"肥效试脸,拟合了肥料效应三元二次方程和一元二次方程。通过三元二次方程得出,在该土壤条件下氮、磷、钾最高施肥量为(kg/hm2)N-P2O5-K2O=212.24-57.0-78.3,对应的最高产量为10 551.5 kg/hm2;最佳施肥量(kg/hm2)N-P2O5-K2O=168.4-55.4-63.2,对应的产量为10 432.7kg/hm2。通过拟合一元二次方程得出,在该土壤条件下氮、磷、钾最高施肥量为212.1 kg/hm2、67.0 kg/hm2、64.0kg/hm2;最佳经济施肥量184.1 kg/hm2、63.0 kg/hm2、60.3 kg/hm2。 |

| Abstract: | Field experiment of fertilizer effect was conducted in Jiaohe city,Jilin province.According to quadratic equation of three variables,the highest yield of 10 551.5 kg/hm2 will be reached when N-P2O5-K2O was 212.24-57.0-78.3(kg/hm2).The optimal fertilizer applied was 168.4-55.4-63.2 and yield was 10 432.7 kg/hm2.According to quadratic equation of one variable,the most fertilization N-P2O5-K2O was 212.1-67.0-64.0 kg/hm2 and the most economical fertilization N-P2O5-K2O was 184.1-63.0-60.3. |
